同学们知道,解析几何的基本思想方法是通过坐标法使几何问题代数化.这种方法的最大优点是,能使问题从定性的概观到定量的细微.当然,几何问题的代数化,必须进行运算推理.有时,运算推理的过程是繁冗的.如何有效地化解这种两难纠结,一个明智之举是,在解几中勿忘平几,在解几中寻觅平几.本文有感于此,拟围绕 Students know that the basic idea of ​​analytic geometry is to coordinate the geometric problem by the coordinate method.The biggest advantage of this method is that it can make the problem go from the qualitative overview to the quantitative subtle.Of course, the geometric problem must be algebraic Computational reasoning. Sometimes, the process of computational reasoning is burdensome .How to effectively resolve this dilemma, a wise move is to forget a few in the solution, how many in the search for a few. , To be around
